摘要： A publication system effective and secure to the publication agency and a user is provided for the publication agency, and a signature verifying function using the published signature log entries is provided for the user. The publication agency publishes a signature log entry received from the users on the Web, and acquires a time-stamp at the time of the publication, and transmits the time-stamp together with a publication notice back to the user. The publication agency also has the signature log, and either discloses part of the log at regular intervals in a newspaper or the like, or produces publication-purpose data based on the signature log entry received from each user, and publishes the data in the newspaper. The publication agency, after the newspaper publication, transmits the signature log of the publication agency to the user.

摘要： The invention provides a method for verification having a structure that reflects reliability of a signature history properly for a hysteresis signature used for verification based on the signature history, and provides a method for arbitration and an arbitrator apparatus that solve a dispute on correctness of a signature based on the method for verification. Furthermore, the invention provides a method for managing history that mitigates the signature history management burden on a signer. Reliability is set on a signature forming record that is a component of a signature history, reliability of the signature history is calculated based on the set reliability, and the calculated reliability is output as reliability of a verification result. The invention provides a method for verification having a structure that reflects the reliability of a signature history properly and a method for arbitration and an arbitrator apparatus that solve a dispute on correctness of a signature. Furthermore, providing a signature history storage service apparatus mitigates the signature history storage burden on a signer.

摘要： A network system capable of preventing the leakage of a confidential file by an inadvertent act of a transmitting party and capable of meeting the requirement for an arbitrary file format is disclosed. A label indicating a security level (“confidential” or “unclassified”) is attached to the file in a client terminal, which transmits the labeled file outside. A transmission management program on a gateway server checks the label of the file, and in the case where the security level is “unclassified”, transmits the file to an external network. Also, a label management program manages the labeled file in the client terminal.

摘要： An electronic document authenticity assurance technique and an information disclosure system both of which can compatibly realize the assurance of the authenticity of disclosure documents and the deletion of information inappropriate for disclosure. An electronic document is divided into constituent elements and an electronic signature is affixed to an arbitrary subset of a set including all the constituent elements. Otherwise, an electronic signature is affixed to data obtained by binding each of the constituent elements to information specifying the relationship between a respective one of the constituent elements and the structure of the electronic document. Otherwise, the hash values of the respective constituent elements are calculated and an electronic signature is affixed to data obtained by binding the calculated hash values together. Otherwise, random numbers generated for the respective constituent elements are bound together, then the hash values of the respective random-numbered constituent elements are calculated, and then an electronic signature is affixed to data obtained by binding the calculated hash values together.

摘要： The present invention provides an electronic document authenticity assuring method in which a series of procedures concerning redactable signature are divided into procedures dependent on a document to be signed and procedures dependent on a redactable signature method. Further, the present invention provides program codes that realize the divided procedures and a system comprising apparatuses for implementing those program codes. According to the present invention, even when type of electronic document to be signed is changed or added to, it is sufficient to add a procedure dependent on a document to be signed, without changing procedures dependent on redactable signature methods. Similarly, even when a redactable signature method is to be changed or added, it is sufficient to add a procedure dependent on the redactable signature method without changing procedures dependent on document to be signed.
